T extends AsciiRendererOptions	AsciiRendererOptions

Accessors

characterFramebuffer

Get Signature

get characterFramebuffer(): Framebuffer

Defined in: renderers/AsciiRenderer.ts:583

Get the character framebuffer, whose pixels define the ASCII characters to use in the grid cells.

Pre-built ASCII renderers like 'brightness' write to this buffer automatically based on your settings. In 'custom2D' renderers, you must write to it manually in your draw() function.

Example

let characterFramebuffer;
let primaryColorFramebuffer;
let secondaryColorFramebuffer;

let asciifier;

function setup() {
  createCanvas(400, 400, WEBGL);
}

function setupAsciify() {
  // Get the asciifier instance
  asciifier = p5asciify.asciifier();

  // Enable the default custom renderer
  asciifier.renderers().get("custom2D").enable();

  // Assign the ascii renderer's framebuffers to a global variable
  characterFramebuffer = asciifier
    .renderers()
    .get("custom2D").characterFramebuffer;
  primaryColorFramebuffer = asciifier
    .renderers()
    .get("custom2D").primaryColorFramebuffer;
  secondaryColorFramebuffer = asciifier
    .renderers()
    .get("custom2D").secondaryColorFramebuffer;
}

function draw() {
  // Draw a rectangle with the character 'A' to the character framebuffer
  characterFramebuffer.begin();
  clear();
  asciifier.fill("A");
  rect(0, 0, 100, 100);
  characterFramebuffer.end();

  // Makes all ascii characters on the grid white.
  primaryColorFramebuffer.begin();
  background(255);
  primaryColorFramebuffer.end();

  // Makes all cell background colors black.
  secondaryColorFramebuffer.begin();
  background(0);
  secondaryColorFramebuffer.end();
}

Returns

Framebuffer

framebufferOptions

Get Signature

get framebufferOptions(): object

Defined in: renderers/AsciiRenderer.ts:530

Get the framebuffer settings used to configure all internal framebuffers for the renderer.

Returns

Name	Type	Description	Defined in
antialias?	boolean	Whether to perform anti-aliasing. If set to true, 2 samples will be used by default. The number of samples can also be set (e.g., 4). Default is false.	renderers/AsciiRenderer.ts:53
channels?	number	Whether to store RGB or RGBA color channels. Default is to match the main canvas, which is RGBA.	renderers/AsciiRenderer.ts:77
density	number	The pixel density of the framebuffers. Always fixed to 1, since they are used for offscreen rendering.	renderers/AsciiRenderer.ts:62
depth?	boolean	Whether to include a depth buffer. Default is true.	renderers/AsciiRenderer.ts:59
depthFormat?	any	Data format of depth information. Either UNSIGNED_INT or FLOAT. Default is UNSIGNED_INT.	renderers/AsciiRenderer.ts:71
format?	number	Data format of the texture. Either UNSIGNED_BYTE, FLOAT, or HALF_FLOAT. Default is UNSIGNED_BYTE.	renderers/AsciiRenderer.ts:74
height	number	Height of the framebuffer. Always matches the grid rows.	renderers/AsciiRenderer.ts:68
stencil?	boolean	Whether to include a stencil buffer for masking. depth must be true for this feature to work. Defaults to the value of depth (which is true).	renderers/AsciiRenderer.ts:80
textureFiltering?	any	How to read values from the framebuffer. Either LINEAR (nearby pixels will be interpolated) or NEAREST (no interpolation). Default is NEAREST.	renderers/AsciiRenderer.ts:56
width	number	Width of the framebuffer. Always matches the grid columns.	renderers/AsciiRenderer.ts:65

transformFramebuffer

Get Signature

get transformFramebuffer(): Framebuffer

Defined in: renderers/AsciiRenderer.ts:463
